Mechanical Booster Pump PMB-040C, PMB-060C
By using together with dry vacuum pumps, oil rotary vacuum pumps or water-sealed vacuum pumps, mechanical booster pumps can increase pumping speed in the range between 10kPa to 0.1 Pa, where roughing pump pumping speed drops.
Features
These pumps use no oil in the pumping chamber resulting in stable performance even when evacuating water vapor or solvent vapors.

SI units are used in this specification. The following conversion can be used for non-SI units.
Ultimate pressure：6.7×10-1 Pa = 5×10-3 Torr,
Pressure：0.05/0.1/0.2/0.3 Mpa = ~0.5/0.1/2/3 atmospheres
*1 Measured value at 13 Pa
*2 Measured by pirani vacuum gauge (with standard backing pump and oil).
The value would be 6.7 x 10-2 Pa when measured with a McLeod vacuum gauge.
*3 00 VAC 50/60 Hz; 200 VAC 60 Hz; 3-phase
*4 Pump oil types other than the standard type are available. Contact ULVAC.
*5 W = width, D = depth, H = height
